There is no clear link between weakly positive anti-PM-Scl antibody and allergic purpura, but the symptoms are basically similar, and both need to be treated with ketorolac tromethamine, cyclophosphamide and azathioprine.
Weakly positive anti-PM-Scl antibody may be a connective tissue disease such as polymyositis, which is an autoimmune disease, and requires admission to the hospital to complete MRI, electromyography, muscle biopsy and other tests to clarify the diagnosis, and to give ketorolac aminotriol, methylprednisolone and other hormones, immunosuppressant drugs such as cyclophosphamide, and gammaglobulin passive immunization therapy.
Anaphylactic purpura is a vasculitis caused by IgA deposition in the vessel wall. It can be treated with antihistamines such as promethazine hydrochloride, vitamin C, hormones such as prednisone and hydrocortisone, immunosuppressants such as cyclophosphamide, and heparin anticoagulation.
If medication is needed, it is recommended that it be used under the guidance of a doctor to avoid unauthorized use. If there is joint pain, skin rash, low fever symptoms serious and persistent can not be relieved, it is recommended to go to the hospital in time to clarify the specific causes, under the guidance of the doctor to take reasonable methods of treatment.
